From 76c52bbe5e5ffc6812dcd49729c09f5a207b4a9a Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Fri, 13 Sep 2013 11:32:56 -0700 Subject: [PATCH] hv: move "client/server_monitor_pending" bus attributes to dev_groups This moves the "client_monitor_pending" and "server_monitor_pending" bus attributes to the dev_groups structure, removing the need for it to be in a temporary structure.
